How to insulate a crawl space
To explain how, we must first address why we insulated crawlspaces in the past. In many homes, we are venting outside air into the crawlspace as a means to dry the crawlspace. Crawlspaces were insulated as a means to combat this cold air from entering the living space. The crawl space vents not only make the moisture problem worse, but they also bring unconditioned hot and cold air into the crawlspace. The crawlspace insulation industry has risen as result of bad crawlspace science.
Crawlspace Vents bring in hot, humid air in the summer that heats the air conditioning that is traveling through your air ducts. Before the air conditioning reaches the living space, the air conditioning system has had to work overtime to produce the cold air you are feeling. This outside summer air raises the humidity level of the crawlspace air that travels into the living space and works against the air conditioning as the moisture needs to be dried out of the air of the living space.
In the winter, even if the vents are closed, freezing, cold air enters the crawl space through vents, porous foundations, and around pipes and wires to the outside. This causes cold, uncomfortable floors and higher heating costs. This cold air works against the heating system causing it to work more to produce the heat you desire. Crawlspace Vents are the major contributor to heating and cooling loss in a crawlspace.
Since vents are the largest reason for heat loss in a crawlspace, we must seal and insulate them. We cannot do this without first sealing the moisture from the ground floor and foundation walls. This is why The Crawlspace Company recommends our AmeriBrite Encapsulation System as the only way to properly insulate a crawlspace.
Insulating a crawlspace with a encapsulation system
Building Scientists, and the US Department of Energy both agree that a vented crawlspace in warm and cold climates is a bad idea. With the AmeriBrite Encapsulation System, your vents and any other outside source of air leakage into the crawlspace will be sealed permanently. Vents will be closed outside and sealed on the inside with 2″ thick foam insulation and polyurethane caulk. This will save you money in energy costs and create a more comfortable and healthier living environment.
Installing a crawl space encapsulation system and sealing off the outside air is the first step. If sealing is not enough, then adding crawl space insulation is the next step. Most insulation methods are not effective until the crawlspace is dry and the outside air is eliminated from entering your crawlspace. The cost of crawl space encapsulation pays for itself with its energy efficient benefits.
